About the 01246 dialling code
01246 is the UK geographic dialling code for Chesterfield, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Chesterfield area.
A full Chesterfield number is normally written as 01246 XXXXXX. You can dial the local part on its own from within the same area, or the full number from anywhere in the UK.
Because of UK number portability and internet calling, a 01246 number no longer guarantees the caller is physically in Chesterfield. Fraudsters also "spoof" local codes like 01246 so an unknown call looks like a nearby business or neighbour — so treat an unexpected call on what is actually said, not on the area code alone.

History of the 01246 code
The code was 0246 until PhONEday, 16 April 1995, when a "1" was inserted after the leading zero to create 01246.
In the letter-dialling era the code had the mnemonic CH6 — on an old rotary dial, the letters CH (from Chesterfield) sat on the same holes as the digits 246, so subscribers literally dialled the start of the town's name.

Is a call from 01246 safe?
Most 01246 calls are ordinary local calls from Chesterfield homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01246 prefix so you are more likely to answer. Never share bank details, passwords or one-time security codes with an unexpected caller, even when the number looks local — hang up and call the organisation back on a number you have verified yourself.
To call a 01246 (Chesterfield) number from outside the UK, drop the leading zero and dial +44 1246 followed by the local number.
